Usage Guidelines
The show interface cable modem command displays the cable modems that are known to be using or
were last using the specified cable interface. When a cable modem goes offline, it remains associated
with its last known cable interface and is shown as "offline" in the command's display for 24 hours.
The CPE devices associated with offline cable modems remain in the command's display either until
their cable modem has been offline for 24 hours or until the device's Address Resolution Protocol (ARP)
entry times out (the default value is 4 hours), whichever comes first.
